I would strongly, strongly recommend you get a waterstone (a Norton 1000grit/4000grit combo waterstone is fine), and practice on some of your cheaper knives to gain confidence, then sharpen your expensive knives. Most electric sharpeners are garbage and you can get a much sharper edge doing it manually with a waterstone.

I thought it would be incredibly difficult to use a waterstone, but it's very simple after a little practice.

I have little use for steels, and grinder stone style knife sharpeners(powered or hand). One has to have a PhD to use either one of those.

Steels need great skills or you will whittle the knife away.

Stones will eventually load up with grindings that you end up in a good workout doing nothing to your knife. Stones do need maintainance.

I use a simple carbide insert "V" style of sharpener like the Smith Jiffy Carb Sharpener or AccuSharp. Actually they dress the blade in removing the blade edge curl. They remove the least amount of the blade material to get you going.
